This invention consists in so making car tridges for breech-loading fire-arms as that the part which contains the powder and ball is separate and detached fi'om that which contains the fulminate. This is accomplished by making the cartridge substantially in separate parts, which are only brought together of reference indicate like in the act of loading. The part which contains the powder and ball is a hollow cylinder, closed at the end which receives the powder, but such end having a small perforation at its center, to enable fire from the explosion of the fulminate to reach the powder within. This end of the cylinder is inclosed,'when the arm is loaded, within a cylindrical cap, one end of which is closed, said end having a recess that projects outward from its center,

which recesscontains the fulminate, and which, when the cap is placed over the other part of the cartridge, is opposite the perforation that reaches the powder.

The cap has a flanged head, by which it'is withdrawn from the breech ofa gun after firing, and on one side it has an oblong slot, which allows a portionof the side of' the inner cylinder to be forced, out by the explosion of theconnect thecap and inner' for the purpose of drawing powder, so as to cylmder together,

I have endeavored to avoid this danger by making a cartridge whose shell is in two parts, detachable and separate. I also provide against the escape of gas from the rear of the cartridge when it is fired.

In the example of my invention here given, cylindrical case which receives the powder and ball. It is plain, the rear end that receives the powder being closed, save by a'small perforation to allow the explosion of the fulminate to reach through it to the powder. The place of the perforation is marked 0, and it may be dented outward to bring the powder into close proximity with the fulminate. The letter B designates a cylindrical case of larger diameter than the other, so that it can be placed over its end, as seen in the .description. The counterbore of the gun may be enlarged to receive the-case B, or that part of case A which is inclosed may be reduced in diameter if the bore is not enlarged. This case B forms a cap to the rest of the cartridge, and it has a flange at the edge of its closed end, to enable it to be thrown out of the breech of a gun by The center of the closed end of the cap or case B is projected, as seen at D, to form a recess within for a charge of fulminate, which may be covered. and protected by a waterproof covering. An oblong slot, F, is cut on one side of the case or cap B, to enablethe case A to be attached or made to adhere to 'the outer case by the efiects of the explosion of the cartridge, which willforce the adjacent part of case A into or against the edges of the slot, sov as to enable both cases to be withdrawn from a gun or pistol by applying force. to-the flange E of the outer case.
